Riverbank filtration (RBF) is an efficient and
low-cost natural alternative technology for water supply
application in which surface water contaminants are removed
or degraded as the infiltrating water moves from
the river to the pumping wells. In this study, a full-scale
RBF site consisting of three vertical wells installed 50 m
from Nile bank was investigated. The RBF systems are
particularly well suited for providing better water quality
than withdrawal directly from the Nile River to produce
drinking water for New Aswan city. The study is carried
out by taking samples over 1 year from riverbank filtrates
wells, Nile River (as induced surface water), and some production
wells were collected and analyzed. Physicochemical
and microbiological measurements such as turbidity, dissolved
oxygen, total suspended solids, total organic carbon,
total dissolved solids, electrical conductivity, pH, Fe, Mn,
NH3, NO2, NO3, PO4, Ca, Mg, Na, K, HCO3, SO4, Cl, total
bacteria, and total coliform were carried out. The results of
bank filtrate were compared with those of the natural groundwater
and previous reported Nile water. Chemical and bacterial
quality parameters of RBF are under the allowable limits
for drinkingwater.Moreover, bank filtration is simultaneously
improved the ambient groundwater and cleaned Nile water in
the studied area. Result of this full-scale RBF plant showed
the effectiveness of riverbank filtration as a proven treatment
technique in Nile Valley with a fraction of cost comparing to
conventional surface treatment plants.
